| 摘 要： | 鄂尔多斯盆地奥陶系以碳酸盐岩溶蚀孔洞为主要的油气储集空间.通过100余口钻井300余个岩石薄片,以单个薄片的溶斑为研究对象,发现孔洞的充填程度在区域上具有明显的分带性,东、西部地区发育的孔洞被完全充填,孔隙消失殆尽,而中部地区孔洞被部分充填,存在大量的剩余孔隙,为油气储集提供了有利空间.孔洞充填物主要为白云石、方解石以...

| Abstract: | Ordovician carbonate hydrocarbon reservoir spaces are mainly corroded cavities in the Ordos basin.The dissolve freckle of single chip as the research object,about 300 rock chips of more than 100 drilling wells are observed.The results show that the filling degree of cavity is distinctly zoning.The cavities in the eastern and western area are completely filled and pores disappear.But,the cavities in the central area are partly filled,there are a lot of pores remained which provide advantageous spaces for oil... |
